help i have stretched my belly to the max

i have a petite frame and already put on 25 lb at 28 weeks. this is my second. i put on 25 total the first time. i am sooooo uncomfortable and have a hard time eating and breathing. i wonder if i can try to lose a pound or two. it’s hard for me to sit/lay and i get tired quickly. how is there still 3 months left??????
